Is that Police-speak for, "I got nuthin"?
In DC it means that I'm done for the rest of the tour.
I love the codes. In my summer job in New Jersey we had walkie-talkies because we were spread out over a large area. We had to use the codes, I wonder if they are similar?10-4 = message received10-17 = en routeSo if someone wanted you to come over you would have to say "10-4, 10-17".10-1 = one of the rides has been urinated on10-2 = you can probably guess
For us 10-4 meant a couple of things - an acknowledgement, copy, or riding with a partner. Don't have anything for being defecated on except maybe an expletive I wouldn't want to mention.
